linear and exponential graphs and x,y intercepts
I have two lines one linear (y=mx+c) and one exponential (y=c^bx) and
they intercept each other. I believe it is possible to calculate where
the lines intercept. Although I can do this by graphing the data, it
takes time and allows for user error so a calculation would speed
things along greatly.
So for the first line using the equation y=mx+c the numbers for the
13kPa line are y=0.0021x+9e-16
And for the exponential line (y=c^bx) which we produce to using the
myograph is y=0.0022^0.0046x (^=Exp)
I know that the two lines intercept at 1613. But no matter what I try

In Excel how do you set up a 3 variable linear programming
problem on a spreadsheet with a a number of constaints
See the tutorials and examples at www.solver.com.
Or, search your drive for the file solvsamp.xls, which is installed when
Solver is installed and which has a 3-variable nonlinear example that is
easily converted to linear.

were using A1.

I am kind of new to excel and was wondering if excel is capable of

one case i want to go from 0 to 10 in increments of 2 and in other
cases i want to go from 0 to 10 in increments of 5. The number of cells
change. Is it possible for excel to do this w/o having to specify the
number of cells needed?

I have a dataset with a (straight) line fit to it

do I take line with a different slope and force fit it to
my data and optimise this new fit (i.e. get a new,
obviously smaller, regression value that's a maximum for
the forced slope with my data)? It's sort of the opposite
of forcing a line through zero, I think. Anyway, is it
possible, and if so where do I go to find out how to do it?
I think you have to do it the old fashioned way. Attached is a
